In the early 1900s, Robert Millikan used small charged droplets
of oil, suspended in an electric field, to make the first
quantitative measurements of the electron’s charge. A
0.79-μm-diameter droplet of oil, having a charge of
+e, is suspended in midair between two horizontal plates
of a parallel-plate capacitor. The upward electric force on the
droplet is exactly balanced by the downward force of gravity. The
oil has a density of 860 kg/m3, and the capacitor plates are 6.0 mm...
